1x4 8K HDMI 2.1 Splitter

The BZBGEAR BG-8K-DA14 distributes a single HDMI source to four displays simultaneously. It supports bandwidth up to 48Gbps and handles 8K at 60Hz or 4K at 120Hz with 12-bit colour depth. Installers and home-theatre owners use it to feed multiple screens from one console, streamer or media player.

Auto Downscaling for Mixed Displays

The splitter automatically scales 8K signals to 4K or 1080P on each output so older screens stay compatible without manual setup. Advanced EDID management negotiates capabilities across all four ports, reducing handshake failures when displays differ. This replaces basic splitters that force every output to the lowest common resolution.

Sustained 48Gbps Operation

The unit maintains full 48Gbps FRL throughput across all ports during extended sessions, not just in short bursts. HDCP 2.3 compliance stays active continuously, preventing signal drops with protected 8K or 4K120 content. VRR, ALLM, QMS, QFT and SBTM protocols remain stable under constant load, keeping gaming and cinema playback smooth.

Questions about this item

Does the 19-pin HDMI input fit a standard Type A cable?

Yes, the single HDMI IN uses a standard Type A 19-pin female connector, so any compliant HDMI cable plugs straight in.

What is the step users miss when setting up the auto downscaling feature?

Connect all four displays first; the splitter reads each sink EDID, then automatically scales 8K to 4K or 1080p per output without further menu changes.

Will the HDCP 2.3 handshake need a firmware update later?

The unit is HDCP 2.3 compliant out of the box; no firmware process is described, so normal power cycling is the only routine action.
